    I have one of these relics with a pretty hacked up harness. Does anybody have a pin out on the main connectors? I have the wiring diagram in the software and the manual but none of them show pin numbers on the main connectors. It is set up for EDIS ignition if that matters much.
    Thanks!

    Thanks, but that diagram is the exact same thats in the software help file:)I need to know what wire goes where in the main connectors, in most OEM connectors each pin has its own number-thats what i want to know!

    If you haven't figured out yet, the header pin locations are on the drawing at the left side. A is one connector and B is the other. The headers have numbers and locations on them, just very tiny and difficult to see.

    Ohhhhhh.....Disregard that...
    Let me know if I can help with the pinout. I guess the drawing doesn't show the locations. I have a few harnesses here I can help with the locations.

    Im in the SAME boat, I bought a Mustang turbo with this system (Gen 7) and there is no one that has software old enough to even tune the car and I don't have laptop with a 10 year old OS.

    My point is, i need the Gen 7 ecu wiring diagram also,lol

    Sorry guys, I've been a bit lazy with my gen 7 stuff lately I'll try to finish the pinout this week. I'll even try to make a chart with the small differences between the gen 7 and fast classic harness. I also have the software CD but dont know how to upload it... I have Windows 7 working with the gen 7. There is a good writeup om the web somewhere om how to make newer Windows systems work with the good 'ole gen 7.

    Here are my pinout chart. Somehow i couldnt upload my Word documents so I had to take pictures of the printed papers.
    The wire colours may differ a bit from harness to harness, especially cam/crank sensor wires.

    1accel7+ is a pic of connector #2
